For some reason, I'm reminded of the 486 math processor  screwup of 1992 (?).  As I vaguely recall, the math coprocessor might have errors in the fourth digit of significance.  Intel offered to replace the affected chips.

I think it is the Pentium FDIV bug. IIRC only the server CPU was replaced in the whole office, don't remember why.

From TFA: microcode can't fix it, lol. AMD is not affected. Shouldn't Intel do recall again?

I think they might go bankrupt ;)

haha I wish. If people tried to sue intel, the US govt would throw the plaintiffs in jail. Oh, and here's another Pretty Good One https://arxiv.org/pdf/1710.00551 looks like all RAM is fucked hahaha

And think of all the work for sysadmins swapping CPUs & swapping systems... I think we are going to be stuck with OS level fixes that are potentially very bad for performance. People are already grumbling about the potential impact on AWS & other cloud providers... Speculation about a 30% performance hit?!
